Description
Technical field
The utility model relates to a kind of chimney for fume emission, particularly relates to a kind of glass fiber reinforced plastic and pylon chimney stack.
Background technology
At present, the large-scale chimney that chemical enterprise, coal-burning power plant etc. use traditionally more to be adopted concrete for making or adopts steel stack, cost of manufacture is high, long construction period, in actual use, by the heating repeatedly of discharge flue gas, inner liner easily comes off, and needs to carry out preservative treatment to the inwall of chimney every a period of time.
The main part of fiber glass reinforced plastic chimney is made up of winding process, Wrapping formed glass fiber reinforced plastics product is made up of laminate structures, fiber glass reinforced plastic chimney is now widely used in electric power, chemical fertilizer, chemical industry, smelt, the industries such as oil, as the treatment facility of corrosivity or high-temperature flue gas, fiber glass reinforced plastic chimney can not need insulation layer or the insulation of thermal protection layer just can realize good heat insulation effect, this is that the characteristic of conducting heat slow due to glass-reinforced plastic material determines, in use procedure, fiber glass reinforced plastic chimney is due to himself light specific gravity, the wind load be subject to is large, external turret is needed to support, and external turret needs the wind load sharing chimney uniformly.
According to the feature of system cloud gray model, because tail gas enters chimney through absorption tower, in treated flue gas, water vapour content is higher, when being discharged by chimney, after reaching a certain height, just there will be dew point, and formation has the inwall that certain corrosive drop is attached to chimney, causes dew point corrosion to chimney, therefore, selection for fiber glass reinforced plastic chimney inner liner is very important, and for reaching the requirement of strength of glass fiber reinforced plastic wall thickness, the selection of the armature bed of material is also very important.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of supporting capacity is strong, stabilized structure, corrosion-resistant, resistant to elevated temperatures glass fiber reinforced plastic and pylon chimney stack.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of glass fiber reinforced plastic and pylon chimney stack, comprise chimney internal cylinder and be supported on the support outside inner core, described inner core comprises the glass fibre reinforced plastic cylinder of multistage by Flange joint, the outside of described inner core is provided with stiffening ring, described stiffening ring interval same distance is arranged, be provided with between described support and inner core and win in succession, the barrel of described inner core comprises inside lining anti-corrosive layer, middle enhancement Layer and exterior cover sheets, described inside lining anti-corrosive layer is resin material layer, described middle enhancement Layer comprises non-twist winding roving layer and glass fiber plain weave layer of cloth.
As preferred technical scheme, described resin material layer is the ethene improved fundamental mode resin of epoxy novolac.
As preferred technical scheme, described support is divided into multistage, and segmentation place of support is staggered with segmentation place of inner core, and segmentation place of described support is provided with the arm-tie be looped around outside inner core.
As preferred technical scheme, described support is four post pylons.
As preferred technical scheme, the top of described inner core is provided with lightning rod and alert boat lamp.
Owing to have employed technique scheme, a kind of glass fiber reinforced plastic described in the utility model and pylon chimney stack pylon share by arm-tie and winning in succession the wind direction load and vertical load that fiber glass reinforced plastic chimney bears, make chimney more firm, reduce the moment of flexure of glass fiber reinforced plastic, for side wall strength and the corrosion-resistant degree of reinforcing glass steel stack, select enhancement Layer and the anticorrosive coat of more high strength, heat stability is strong, increase the whole service life of chimney, reduce use cost.
